Abstract Very little is known on Ctenomys pilarensis, as it has rarely been studied. We conducted a preliminary study on its burrow use by implementing a capture-mark-recapture method. Between February and June 2022, 12 different Pilar tuco-tucos were captured and chipped using MiniHPT8 PIT tags, 7 individuals were recaptured at least once. Our results indicate this species to be solitary, as we found no evidence of burrow sharing. These findings should, however, be viewed with caution due to our small sample size.

Abstract Recently, the Mostela system emerged as an expansion of camera trapping to gain new insights into the assemblages of small-sized and cryptic mammals. Despite being an established technique to study the natural history and ecology of rodents, shrews and small carnivores in Europe, its potential in tropical areas remains unexplored. We present the results of a pilot hybrid survey with conventional trail cameras and Mostelas conducted in a private protected area situated in the Cordillera Occidental of Colombia. We installed eight Mostelas paired with an external trail camera 550 m apart from each other from May to October 2022 in the Mesenia-Paramillo Nature Reserve. The Mostelas recorded two species of small carnivores, the threatened and unknown Colombian weasel (Neogale felipei), and the Long-tailed weasel (Neogale frenata), including several small rodents and marsupials. Mostelas captured a larger proportion of small non-volant mammals that could at least be identified to genus level compared to conventional trail cameras. We found that using baits inside Mostelas yielded a greater number of detections and richness compared to surveys not using them. Finally, we encourage the use of this hybrid system to improve the monitoring of poorly known small non-volant mammals in the Andean cloud forests.

Abstract Longworth live traps are widely used for trapping mouse-sized rodents and shrews. However, they have a number of disadvantages: some have a manufacturing defect, resulting in reduced sensitivity; smaller species of shrews can pass under the treadle, avoiding capture; captured animals can gnaw specific parts of the sidewalls and decrease the durability of the traps. To increase the efficiency of catching small shrews, we added a movable tin ramp to the treadle of the Longworth live traps and used washers to improve the design. To repair and protect traps damaged by captured animals, we used tin patches. The modified traps were shown to be significantly better than the original traps in catching small shrew species (Sorex caecutiens Laxmann 1788, Sorex minutus Linnaeus, 1766). Tin patches reliably protected live traps from further damages by animals and do not affect their catching efficiency.

Abstract Rodents play an important role in the transmission of zoonotic diseases. This study investigated the prevalence of Leptospira spp. and Bartonella spp. in Mastomys natalensis and its ectoparasites (fleas and mites) in selected villages of Morogoro, Tanzania. Mastomys natalensis were captured live in fallow habitats using Sherman® traps and anesthetized using Halothane. Blood samples were obtained from the retroorbital sinus Ectoparasites were removed from the fur using a hard brush and preserved in 70 % ethanol. Real time–qPCR was used to detect Leptospira spp. and Bartonella spp. from Mastomys natalensis blood and ectoparasites respectively. The study revealed a relatively larger number of males than females captures. Leptospira spp. was demonstrated in one out of 100 Mastomys natalensis. For Bartonella spp., prevalence of (14 %) was recorded in mites with a higher proportion in mites from adult male Mastomys natalensis than females. Upon Sanger sequencing, four positive samples showed a complete sequence of the ITS gene. Indicating that all samples belonged to Uncultured Bartonella. Low prevalence of Leptospira spp. and a high prevalence of Bartonella spp. was observed in Mastomys natalensis. Further exploration of rodent pathogens is recommended to raise awareness of the role of commensal rodents in disease transmission via their ectoparasites.

Abstract Tree squirrel species that are successful invaders may modify their behaviour according to the characteristics of the invaded community. We studied the use of space by Callosciurus erythraeus in the main invasion focus established in Argentina, where suitable habitat is highly fragmented and immersed in a rural–urban landscape of the Pampas region. We evaluated habitat use in relation to the dominant arboreal vegetation (evergreen vs. deciduous) based on seasonal trapping data throughout two years and home range size and overlap based on seasonal radio-tracking data in two consecutive years. We captured 476 squirrels with a higher trapping success in areas dominated by evergreen vegetation. Effective home ranges were smaller for females (0.10–0.77 ha, n = 12) than for males (0.9–3.78 ha, n = 3). We observed home range overlap between and within both sexes, suggesting no or low territoriality. Our results support the two working hypotheses on the relatively higher use of areas dominated by evergreen vegetation and on the relatively small home range sizes and large overlapping areas associated to high squirrel density. The flexibility in the use of different type of arboreal patches would be another attribute linked to the invasion success of this species.
作为成功入侵物种的树松鼠会根据被入侵群落的特点改变其行为。我们研究了红胼胝体对阿根廷主要入侵焦点的空间利用，在那里，适合的栖息地是高度破碎的，沉浸在潘帕斯地区的城乡景观中。基于两年的季节性捕获数据和连续两年的季节性无线电跟踪数据，我们评估了栖息地利用与优势乔木植被(常绿与落叶)的关系。我们在常绿植被为主的地区捕获了476只松鼠，捕获成功率较高。雌性的有效范围(0.10-0.77 ha, n = 12)小于雄性(0.9-3.78 ha, n = 3)。我们观察到两性之间和两性之间的范围重叠，表明没有或低领土性。我们的研究结果支持了两种假设，即松鼠对常绿植被占主导地位的区域的利用相对较高，以及松鼠密度较高的相对较小的活动范围和较大的重叠区域。在使用不同类型的树木斑块方面的灵活性将是与该物种入侵成功相关的另一个属性。

Abstract The occurrence of the non-native, greater white-toothed shrew Crocidura russula in the Stavanger area in Southwestern Norway was brought to our attention by two records from the public (from 2012 and 2017). A citizen-science project, based on targeted media-calls between 2017 and 2019, resulted in 78 reported observations. A correct species identity, using photographs and collected specimen, was confirmed for 103 observations from 68 unique localities. Many of the sightings resulted directly from the media calls, but several were made both years before and after (ranging from 2012 to 2021). The minimum area of occurrence was 60 km long and 20 km wide and is characterised by one of the mildest climates in Norway. No clear expansion pattern was evident from the data, though an introduction between 2000 and 2010 seems likely. As only a few other shrew species were reported by the public, it is possible that the white-toothed shrew has outcompeted native shrews in the area. However, this could be biased by the nature of the media call or the commensal lifestyle of the shrew. Media calls beyond the area of occurrence did not result in any reports of the species. The introduction route and origin of the present population remain unclear.

Abstract Although melanism is common in some mammal species, particularly in domestic forms, its occurrence in lagomorphs is rare. We report the first records of melanistic wild rabbit, Oryctolagus cuniculus in North Africa. These were obtained from a camera-trap set in Tiaret governorate, Algeria, in 2019 and 2020. Melanism is restricted to few species of Leporidae, genera Sylvilagus and Lepus. Dark rabbits have been reported to a new subspecies from Camargue (France), however this status is not recognized any longer.

Abstract The recently established Chebera Churchura National Park represents a mosaic of savanna and montane evergreen forest. A report on small mammals (2013) showed their relatively high diversity, but species identification was based only on external morphology. We conducted a new field survey and genetic analyses to shed light on diversity and biogeographical affinities of small mammals in this under-explored national park. Based on results of mitochondrial DNA barcoding, 14 species of rodents and two species of shrews, including Crocidura turba (new to the Ethiopian fauna), were identified. Moreover, a new taxon of gerbils – presumably representing a new species – of the genus Gerbilliscus was discovered. We show that forest and savanna species often inhabit the same localities, which can be explained by the mosaic nature of biotopes. These results document the uniqueness of Chebera Churchura NP, especially in comparison with other Ethiopian national parks, and argue for its protection and further development.

Abstract Orthohantaviruses are a group of zoonotic pathogens that can cause severe and potentially fatal syndromes in humans. Although orthohantaviruses have been documented in Iran, little is known about their potential reservoirs in the country. The present study constitutes the first attempt to detect orthohantavirus infections in rodents in Iran. Sampling was performed in the East Azerbaijan province, during October 2017 and June 2018. To detect orthohantavirus infection, we performed a Pan-hantavirus nested reverse transcription-polymerase chain reaction targeting the large segment of the viral genome using consensus primers on lung tissue samples. We identified Tula orthohantavirus for the first time in Iran and from Dryomys nitedula sensu lato (s.l.) (Gliridae), a non-muroid host. There are two possible interpretations for this finding: an interspecies spillover or the presence of a broader primary host/reservoir list. However, at present, we do not advocate for either interpretation, but instead, argue for further accumulation of relevant data. Phylogenetic analysis revealed a close relationship between the Tula orthohantavirus identified in this study and those detected in Turkey. Nevertheless, comprehensive field studies, as well as full-length sequence analyses, are required to gain a better understanding of the potential reservoirs, ecology, and epidemiological cycle of the virus in Iran.
正汉坦病毒是一组人畜共患病原体，可引起人类严重和潜在致命的综合征。虽然伊朗已记录了正汉坦病毒，但对其在该国的潜在宿主知之甚少。本研究首次尝试在伊朗的啮齿动物中检测正汉坦病毒感染。2017年10月至2018年6月在东阿塞拜疆省进行了抽样。为了检测正汉坦病毒感染，我们在肺组织样本上使用共识引物，针对病毒基因组的大片段进行了泛汉坦病毒巢式逆转录聚合酶链反应。本研究首次在伊朗鉴定出图拉正汉坦病毒，该病毒来自一种非类宿主——灰鼠科(Gliridae)的nitedula sensu lato (s.l)。对这一发现有两种可能的解释:种间溢出或存在更广泛的主要宿主/宿主列表。然而，目前，我们不主张任何一种解释，而是主张进一步积累相关数据。系统发育分析显示，本研究中发现的图拉正汉坦病毒与在土耳其发现的病毒之间存在密切关系。然而，需要进行全面的实地研究和全长序列分析，以便更好地了解该病毒在伊朗的潜在宿主、生态和流行病学周期。
